I have /home on a bcache partition - cache device is a 120GB Intel 330 SSD
on /dev/sdb, backing store device a WD Green 2TB on /dev/sdd. Kernel is
3.10.9 installed from the Ubuntu mainline PPA. Was working fine up to
shutdown last night. On bootup this morning, /home would not mount. Running
fdisk shows sdb and sdd are recognised. Extracts from syslog this morning
below. Any suggestions on how to recover the partition?
